Abstract
A method of producing a tris ([beta]-diketonato) iridium, in which [beta]-diketone is made reacted with an iridium compound, is characterized in that the iridium compound is subjected to an activation treatment to thereby activate the iridium compound, and then react the [beta]-diketone. The activation treatment includes: (a) an alkali treatment where an alkali is added to a solution of the iridium compound to adjust a pH of the solution closer to an alkali side than that of pre-addition of alkali and pH 10 or higher; and (b) an acid treatment where an acid is added to the alkali-treated solution to adjust a pH of the solution closer to an acid side than that of pre-addition of acid and simultaneously pH difference to fall within 0.1-10. The method allows, when a tris ([beta]-diketonato) iridium is produced, a synthetic reaction to advance with no range of the [beta]-diketone to be coordinated to the iridium limited.

[chemical formula 3]
[chemical formula 4]
[chemical formula 5]
[chemical formula 6]
Incidentally, it is in iridium chemical combination as the specific operation for reacting the iridic compound of activation and beta-diketon
Beta-diketon is added in thing solution.As the opportunity that the beta-diketon is made an addition to iridic compound solution, can terminate in activation process
Add beta-diketon in iridic compound solution afterwards, it is also possible to before activation process terminates in iridic compound solution add β-two
Ketone, then carries out activation process.
When adding beta-diketon in the iridic compound solution after activation process terminates, can be straight by the solution after activation process
Connect for synthetic reaction.But the species of starting compound is sometimes depended on, precipitate can be produced because of activation process.The situation
Under, can filter and reclaim precipitate and be dispersed in water it, and be added to beta-diketon.And, by activation
Solution after reason adds beta-diketon in the dispersion soln of precipitate, so as to carry out the synthetic reaction that three (beta-diketons) close iridium.
On the other hand, as the technical meaning of the addition beta-diketon in the iridic compound solution before activation process terminates, bag
Include following two situations：Adding beta-diketon before carrying out both alkali process and acid treatment in iridic compound solution in advance
Situation, and be added in the midway stage of activation process, i.e. in the centre of alkali process and acid treatment in iridic compound solution
Add the situation of beta-diketon.
When beta-diketon is added in the iridic compound solution before activation process terminates, do not enter in the addition stage of beta-diketon
Row three (beta-diketon) closes the synthetic reaction of iridium.Start synthetic reaction by terminating the acid treatment of activation process.
As described above, being allowed for reason as 3 kinds of patterns of the mode that beta-diketon is made an addition to iridic compound solution, it is
Because, in order that the synthetic reaction that three (beta-diketons) close iridium is carried out, it is necessary to activate iridic compound, and iridic compound activation
Manifested by the end of both alkali process and acid treatment.
Additionally, it is contemplated that during addition opportunity of 3 kinds of beta-diketons as described above, add as the alkali in activation process, acid
" solution before alkali (acid) addition " of the benchmark of the pH adjustment of added-time refers to the solution before the addition alkali (acid) as shown in word
Meaning.That is, when beta-diketon is added after the activation process of iridic compound terminates, " solution " before alkali addition is that iridic compound is molten
Liquid.On the other hand, when adding beta-diketon in iridic compound solution in advance before activation process (alkali process) is carried out, alkali addition
Preceding " solution " is the mixed solution of iridic compound solution and beta-diketon.In addition, in alkali process and the intermediate step of acid treatment
When adding beta-diketon in iridic compound solution, " solution " before alkali addition is only iridic compound solution, but " molten before acid addition
Liquid " is the mixed solution of iridic compound solution and beta-diketon.
And, when adding beta-diketon in iridic compound solution, depending on its species, the pH of iridic compound solution can change
(not changing mostly).When the mixed solution of iridic compound solution and beta-diketon is equivalent to solution before above-mentioned alkali (acid) addition,
The pH of the solution uses the value of the state of mixed solution.In addition, being applied equally to add and calculate by above-mentioned alkali (acid)
